Abstract Aim Treatment of complex anal fistula (CAF) is challenging, often requiring multiple operations due to a high failure rate. The plethora options attests the lack panacea. Endorectal advancement flap (ERAF) carries advantages no sphincter division, contour defect canal and perineal wound. rate this procedure ranges between 15% 60%. Although traditionally described rhomboid (tongue‐shaped) flap, an elliptical (curvilinear) was introduced try improve results. This study aimed describe elliptical‐shaped ERAF performed by senior authors others compare rates ERAFs for CAF. Method A retrospective review all patients who underwent CAF 2011 2017 undertaken. Patients were divided into two groups based on type flap: or elliptical. main outcomes measures postoperative persistent recurrent fistula. Results Seventy‐six procedures identified in 71 patients; 39 had classic 37 configuration with mean follow‐up 13.8 13.9 months, respectively. similar demographic parameters preoperative characteristics. overall 37%, success 64% 62% group. Conclusion shape treatment does not appear influence
